Derivations

Can somene help me understand what we use the ln(K2/K1)=-(deltaH/R)[1/T2-1/T1] equation?

We use this equation to calculate the equilibrium constant K for a reaction at a different, new temperature (K is dependent on temperature).

Specifically, K1 is your currently known equilibrium constant at initial Temperature (T1). Then, given that you know the reaction enthalpy, you use this equation to solve for the new equilibrium constant (K2) at a new target temperature (T2).

The equation is called the Van't Hoff Equation, and it helps show temperature dependence of K! It can be used to find K at different temperatures.

Conceptually, how does a change in temperature effect the equilibrium concentrations?
